Thanks for the attempts at help guys.. The Skyview is getting good power 12.8 volts from the plane's onboard battery as confirmed by checking Pin #'s 1 & #20 as shown in the wiring schematic. All fuses are good. Even if it was booting up with the backup battery, that wouldn't explain why buttons 1/2 no longer work. I spoke with Dynon and they feel the keypad likely went belly up which can cause many weird things to start happening, including the issues that I have. It's really too bad, as the plane only has 198 hrs. on the Hobbs.
The Skyview has been removed from the plane and is going out in the mail tomorrow. Hopefully I'll have it back in less than two weeks working and $450 lighter in the pocket book.
